Group of Zones - Herd? Flock? Pod? Implausibility? Cluster!

Yesterday, Solaris Cluster (aka "Sun Cluster") 3.2 1/09 was released.
This release has two new features which directly enhance support of Solaris
Zones in Solaris Clusters.

The most significant new functionality is a feature called
"Zone
Clusters"
which, at this point, 'merely' provides support for Oracle RAC nodes
in Zones. In other words, you can create an Oracle RAC cluster, using
individual zones in a Solaris Cluster as RAC nodes.

Further, because a Solaris Cluster can contain multiple Zone Clusters,
it can contain multiple Oracle RAC clusters. For details about configuring
a zone cluster, see
"Configuring
a Zone Cluster" in the Sun Cluster Software Installation Guide and the
clzonecluster(1CL)
man page.

The second new feature is
support
for exclusive-IP zones.
Note that this only applies to failover data services, not scalable data
services nor with zone clusters.
